SPECIFICATION forming part Of Letters Patent N0. 630,582, dated August 8, 1899.

Application filed July A.'31, 1897. Renewed March 3, 1899. Serial No. 707,665. (No model.)

T0 all whom, it may concern: t.

Be it known that I, RIOHARDBIGLEY, manu facturer, of the cityof Toronto, in the county of York, in the Province of Ontario, Canada,

have invented certain new and useful Im' provements in Heaters, of which the following is a specification. My invention relates to improvements in hot-water heaters; and the object of the invention is to design a simple and cheaplyconstructed form of heater in which the water may be rapidly heated for distribution;

and it consists, essentially, of a heater com-` heater provided with my improvements. Fig.

2 is a sectional plan through the upper por: tion of the base-section. Fig. 3 isa sectional plan through one ofthe coils. Fig. 4 is a perspective detail of a coil provided with an alternative form of nipple. y

In the drawings like letters of reference indicate corresponding parts in all the Iigures.

A is the ash-pit casing, which is provided with an internal flange. Y Y Y Y B is the bottom section, which is provided with an annular water-space o, extending all around the iirepot.

C is the return-pipe leading into the annular water-space b. r

D is one halt' of the inclosing casing for the watencoils, which rests on a'ilange b', extendingaround the lower section B, and d is a liange extending around the top of the section B, and d are bolt-holes by which the half casing D is connected to the `opposite half (not show-n) by bolts. Y.

E is the smoke-pipe.-

B is the outermost ring of the lower section, which formsV an upper extension to the water-space b. Y

B2 is the inner ring of the section B, whichl is connected to the ring B' by passage-ways b2, and B3 is the. circular water-space at theA center of the section, which is connected with the inner -ring B2 by the passage-ways b3. t lwill be noticed that the passage-ways b2 are located midway between the passage-waysbS,

so as to provide for increased circulation, and

therebyallow the water to be heated rapidly.v

B4 is a ring-boss formed in the center of the lower section B and internally threaded.

E are the circular coils, which consist of outerrings E', inner rings E2, connected to the outer. rings E by the passage-ways e', inner ring E3, connected to the ring E2 .by the passage-ways e2, int'ermediately situated to the passage-ways e', and central water-space E4, connected to the ring E3 by two diametricallysituatedpassage-ways e3, intermediately situated-relatively as to the passageways e2. The central water-space E4 is divided into an upper and lower portion e5 ande6 by an oblique diaphragm e7, extending from the bottom of the center 'water-space to the top at the opposite side, as shown.

The coil Eis provided with top and bottom ring-bosses E5 and E, respectively, which are internally threaded.

F are screw-nipples which connect the ringbosses of one coilor section to that of the adjacent section.

G is the flow-pipe leading from the center of the uppermost coil.`

It will be seen by the way the passage-ways e', e2, and es are arranged that the circulation vofthe water is retarded, and this, of course,

in practice permits of the rapid heating of the water. v

The circulation of` the water is through the lower section in the direction indicated by arrow to the central water-space B3, up through the nipples F, beneath the diaphragm e7, outwardly in the direction indicated byarrow through the passage-ways to one side of the coil, and around and inwardly in the Vdirection indicated by arrow through the passageways to the upper side of theoblique diaphragm, then up through the nozzle, 'whence the course is exactly the same as hereinbefore premised through theother coils.

- It will be noticed that the flow-pipe,-of

-Y which really the nipples connecting the coils are acontinuation, is located in the center of the heater, and consequently the heat from the furnace is imparted thereto as well as to the coils around which the heat circulates IOO and serves to rapidly and quickly heat the water to the desired temperature.

In Fig. I I show an alternative formel' nipple. The ring-bosses are formed substantially as hereinbefore described and internally threaded, and the nipple is externally threaded and screwed directly through the coil. The nipple itself is provided with a ccntral oblique diaphragm 3 and openings 4 at one side above the diaphragm and an opening 5 at the other side below the diaphragm. The lower end of the nipple is reduced in size and externally threaded, while the upper end has an annular shoulder formed above, which has an internal thread which is designed to receive the reduced end of the nipple above.

Although I show my coils as applied to a heater where the heat is received directly from the lire, it will of course be understood that the same principle might be used in radiators.

It will be noticed in my heater that the outside periphery of the coils is situated some distance from the jacket, and consequently the products of combustion are allowed a free passage to the outside ot the coils, which is not the case in any other construction of the circular-coil heater of which I am aware.

\Vhat I claim as my invention is- 1. In a heater, acoil comprisinga plurality of annular water-spaces, passage-ways connecting the annular water-spaces alternately arranged, so that each passage-way of one water-space is opposite the wall ot the adjacent water-space, ringbosses formed on cach side of the central water-space, a diaphragm extending obliquely from one side to the opposite side and suitable flow and return pipes or nipples connected to the bosses as and for the purpose specified.

2. In a heater, in combination, the lower {ire-pot section having an annular substantially vertical peripheral water-s pace provided with an upper inwardly-extending annular water-space having a rounded inner periphery, an intermediate annulaiwater-space and circular' central water-space passage-ways connecting the water-spaces alternately arranged, so that each passage-way of one water-space is opposite the wall ot' the adjacent water-space and an upwardly-extending boss and a suitable central How-pipe and peripherally-placed return-pipe, substantially as described.

3. In a heater, in combination a plurality of coils each comprising a plurality of annular water-spaces,passage-ways connecting the annular water-spaces alternately arranged so that each passage-way of one water-space is opposite the wall of the adjacent water-space, ring-bosses formed in the center of each coil, nipples connecting the bosses and forming the sole support of the completely-separated coils from end to end and the diaphragm extending obliquely in the centerl of each coil between the bosses,substantiallyasldescribed.

4. In a heater, in combination a plurality of coils cach comprising a plurality of annular water-spaces,passageways connecting the annular water-spaces alternately arranged so that each passage-Way of one water-space is opposite the wallof the adjacent water-space, ring-bosses formed in the center of each coil, nipples connecting the bosses and forming the sole support of the completely-separated coils from end to end, the diaphragm extending ohliquely in the center of each coil between the bosses, a bottom water-section of greater diameter than the top coils and a casingalso of greater diameter than the top coils resting on the bottom section formed in two halves divided vertically diamctrically and connected together by flanges whereby the products of combustion are carried through the top of the lire-pot section completely through and around the opposite periphery Y of the top coils, substantially as described.
